 Music is mercurial. I go back to bebop music with Charlie Parker and Dizzy Gillespie. Charlie Parker would play a lick and Dizzy Gillespie would play the same lick and argue about who would get credit over the songs. And it's sort of the cost of success, right? Like if you become big, people are going to cop you. People are going to rip you off. So at first it was Zeppelin.
